My invention has for its object tofurnish an improved apparatus for drying grain, which dry it by the applicaa way that it cannot ill then cool it by the tion of hot air in such burn or scorch it, and w application of cold air, delivering the grain dry and cool, ready for storage or shipment; and it consists in the construction and combination of various parts of the apparatus, as hereinafter more fully described.

A represents the receiver or trough, into which the wet grain is introduced, and from V which it is taken by the elevator B and thence discharged through the spout G into the revolving hopper D, which is attached to the sleeve E, that revolves upon the upper end of the shaft F, which supports the cylindrical drier-case G. The lower part of the drier-case G is perforated with numerous small h is incased with a jacket, H, forming a hot-air space. The interior of the drier-case G is provided with plates I, alternately concave and convex upon their upper sides, and which are perforated with numerous small holes to allow the hot air to pass up freely. The concaved inclined plates I are secured at their outer edges to the case G, and have holes or openings in their centers, through which the shaft F passes, and which are made larger than the said shaft, so that the grain may flow through to the next plate. The convex inclined plates I are attached at their centers to the shaft F, and are made a little smaller than the interior diameter of the case G to leave a space around their outer edges, through which the grain passes to the next plate. The bottom of the case G is made funnel-shaped and has an opening in its center, through which the grain pass oles, and

spout M into the case N, the interior of which isoccupied by a series of perforated plates, O, inclined alternately in opposite directions.

The plates 0 are attached at their upper-and side edges to the walls of the case N, and their lower edges are at a little distance from the wall of said case, to form aspace for the passage of i the grain from the lower edge of one plate to the upper The bottom of the case N is made inclined and with an opening in its lower part, through which the grain passes into any desired receiver.

The grain is exposed, during all the time of its passage through said drier, to the heating and drying action of a current of hot air passing up through the perforations and openings of the plates I, and in through the perforations in the sides of the lower part of the case G.

P is the furnace, the smoke and other gaseous products of combustion from which pass up through the spaces between the series of flattened pipes Q, and escape through the smoke-flue R. The forward ends of the pipes Q open into the chamber S, into which a current of air is forced by the fan-blower T. The rear ends of the pipes Q open into the chamber U, from which the air, heated during its passage through the pipes Q, passes into the drier G. The air is drawn from the drier G, carrying with it the vapors withdrawn from the grain by the exhaust or suction blower V. The grain is thus delivered into the receiver K hot and dry. W is a cap or bonnet, coverin g the rotary hopper D and the upper part of the case G, to confine the air, and which is connected with the upper edge of the case G by a curtain or other flexible connection, X, which prevents the escape of the hot air, and at the same time allows the drier-case G to have a free movement upon the bonnet W. The bonnet WV is stationary, and is connected with and supported by the frame-work of the machine. The case G is agitated while the grain is passing through it by the connectingrod Y, one end of which is pivoted to the lower \part of the side of the drier. The outer end part of the next lower plate.

, while passing through the drier of the connecting-rod Yis pivoted to a crankpin, Z, attached to the driving-pulley A, or to another pulley or crank attached to the drivin g-shaft B, which is driven from any convenient power. The crank-pin Z is made adjustable, so that by moving it from or toward the axis of the shaft less or more motion may be given to the drier, according as it may be nec- 4 essary to have the grain pass slower or faster through said drier. The cooler N is supported upon springs O, and to its side is pivoted the end of a lever, D, the middle part of which is pivoted to the frame-work of the machine, or to some other suitable support, and its other end is pivoted to the side of the drier Gr, so that the movement of the drier G will agitate the cooler N.

The grain, while passing through the cooler N, is exposed to a blast of cold air, which enters through the opening in the bottom of said cooler, and is drawn or exhausted through it, and through the pipe E, by the suction or exhaust blower F The pipes M and E are each made in two parts, connected by a flexible connection or curtain, G, so that the upper parts of said pipes M E may be stationary while their lower parts move with said cooler N.

The elevators B L, the fan-blowers V F, and the rotary hopper D are all driven from the counter-shaft H, which shaft H is driven from the driving-shaft B by a band and pulas new and desire to secure by Letters Pat-- ent- 1.
